Some people can be a bit easier to startle than others. Of course this fact could lead to these poor unfortunate souls becoming a target for the evil pranksters of the world. Then again, sometimes it’s fun to poke the bear because some bears give the best damn reactions.
Case in point: the old man in the video above gives a pretty hilarious and consistent reaction every time the camera guy gets the jump on him. His startled reply is pretty great, especially on repeat.
